    This also provides a solution to bandwidth problems. A signal will be observed to propogate at c in all frames so to conserve energy its frequency must shift. If moving towards a source the frequency is increased an so is the bandwidth. So, if your ISP is slow, just move towards it very very quickly and you should be able to get satisfactory performance. Obtaining equipment to implement this kluge is up to you.

    To be fair, christian apologetics has a huge head start over some of this stuff. St Augustine had a first class intellect and refuted many of Dawkins' arguments before he ever made them. What is interesting to me is that apologetics also tends to refute attacks on science such as creationism. The basic argument is that scientific knowledge should strengthen faith and fighting the obvious goes against St. Paul's urging to do nothing that would harm your brother's growth in faith to take up such a ridiculous cause. For this reason, the greater maturity of apologetics, I expect the creationism debate to be settled within the Church rather than through public debate with scientists, which isn't scientific debate at all. The arguments are simply stronger in apologetics. However, to see this work, there has to be much less pride within the church. I know clergy who just role their eyes at the creationism issue which, I think, puts them is a poor position to look on the creationists as brothers, a first step to having concern for their weak faith.

    Actually my preist covers this sort of thing pretty often since it comes up in the readings. Quite a lot of the clergy in the Episcopal Church are influenced by C. S. Lewis and so consider these issues. Suprised By Joy is the place where he discusses his conversion in detail. Much of it is driven by just these sorts of considerations. The site you give is quite interesting. The exerpt from McGrath's new book is is quite to the point in this discussion.

    Evolution, rightly, avoids discussion of final causes. Theology can't avoid them. Yet, there is inevitability in evolution towards increased diversity while theology has little authority, by its own admission, to dictate to God how things ought to be accomplished.

  12. Re:Let's get this out of the way on Paying for Better Math and Science Teachers · · Score: 1

    I gave a lecture course in Astronomy one summer. I order to get a complete survey of the students, I passed it out before the final. Needless to say, no matter how bad I was at lecturing, there was definite downward pressure on the results owing to my timing. The Department Chair spoke to me about it saying he'd never gotten such a high completion rate and that it was a good thing I was a grad student because if I was faculty I'd be in trouble. Actually, it was two older students who had a large number of complaints (like having to come to class).

    When students judge performance you get some good feedback, but much of my later and better lecturing was improved by just having a better grasp of the subject. I find that the best teachers are the ones who enjoy how other people learn. Putting money into opening up this mode of enjoyment would probably be well spent.

    Well, actually most models I've seen move up and to the left until turnoff. I was not all that happy with the movie because when you set it to one solar mass if givens the wrong luminosity and lifetime but it does get the basics of the evolutionary track. Here is another link that looks like what I remember from grad school, though without references http://zebu.uoregon.edu/~imamura/122/feb23/LMS.htm l. At higher mass what you say may be true. Fig. 10.3 in this link http://www.astro.utu.fi/~cflynn/Stars/l10.html shows a 5 solar mass star behaving as you describe.

    My mistake was getting the direction of the axis wrong, something every one of my teachers has warned me about.

  16. Re:Main sequence evolution on Sun May Be Warming Both Earth and Mars · · Score: 1

    The mass is not changing much, just the number of particles supporting the star against collapse. This means that T goes up to keep P constant in the ideal gas law eqn. This is a slow process so that main sequence evolution is much less dramatic than earlier or later phases. This link to the movie I posted shows a main sequence to red giant evolutionary track. In the movie, the latter phase is much much faster than the main sequence portion. This initial turn off from the main sequence (the perpendicular motion) is driven by the loss of thermotatic control of the core temperature provided by fusion. The core temperature increases, increasing the contribution of radiation which lifts the envelope. The size of the star increase in a way that means that even though the luminosity is increasing the temperature goes down. Mass loss does come into play later.

    Actually they do, only very slowly. There is a famous problem called the Faint Young Sun Paradox http://en.wikipedia.org/wiki/Faint_young_Sun_parad ox that requires extra greenhouse gasses early on for its resolution. Why does the Sun slowly brighten? Basically the central mean molecular weight (bad term) increases as hydrogen is converted to helium. This means more energetic collisions and faster fusion.

    At least for potestants who take St. Paul seriously, it is Grace that supports or allows belief. That would be a two ways street. But, many theologians do identify something in the soul that also seeks God. C. S. Lewis was interested in this and looked at levels of inclination such as loyalty to country, animal's attraction to their keepers as well as darker attractions. His book That Hideous Strength is a good read. Finding some hardwiring for this would not be too suprising I think. I'd imagine that is would be related to things like filial piety http://en.wikipedia.org/wiki/Filial_piety which actually comes in as a commandment.

    I think we actually agree. I reread my post and it clear to me that I said that the lab work shows causation. I would go further and say that our understanding that the sturcture of planetary atmospheres is essentially a priori when the spectra of their costituents is taken as given. An argon atmosphere would be very similar to no atmosphere at all owing to argon's high ionization potential and few transitions. It is the forest of mid-infrared rotational-vibrational transitions from molecules with many degrees of freedom that provides the warming of the surface above what it would be otherwise.

    It is important to distinguish between deduction and inference so that we know the limits of our knowledge. The geologic record is largely consistent with our deductive understanding so we may interpret it as supportive but there is insufficient information there to draw the strongest conclusions. For that, we rely on the lab.
